This week, I’m proud to be in Paris, where the United States and countries around the world are working toward an ambitious global climate agreement at the 21st Conference of the Parties, also known as COP-21.

Since day one in office, President Obama has recognized that climate change is not just an environmental concern. It’s an urgent matter of public health, our economy, and our security.

And we were reminded by Pope Francis earlier this year that acting on climate isn’t just the smart thing to do, it’s our moral responsibility—for the sake of the world’s poor and vulnerable, and on behalf of our kids and grandkids.

That’s why the work going on here Paris—where hundreds of the world’s nations are coming together and collaborating on a path forward—is so important. The global community has never before been so close to consensus on this issue. A historic agreement is at our fingertips.

Today at the State Department’s U.S. Center at COP-21, I spoke about the U.S. Environmental Protection Agency’s (EPA’s) role in this international effort, and how EPA is delivering on President Obama’s climate agenda.

Over the past 7 years, The U.S. has taken a series of ambitious actions to cut the carbon pollution driving climate change, and demonstrate that the U.S. is fulfilling our responsibility to act. All told, the steps we’ve taken under President Obama’s leadership will help the United States reach our national goal of cutting carbon pollution 26-28 percent below 2005 levels by 2025.

Whether it’s the Department of Agriculture’s “Climate Smart Agriculture” initiative to cut carbon pollution by over 120 million metric tons of CO2 equivalent by 2025, or the several dozen utility-scale renewable energy projects that the Department of Interior has permitted on public lands, or NASA’s cutting-edge scientific efforts to monitor Earth-system changes. The list goes on and on.

A centerpiece of U.S. efforts is EPA’s Clean Power Plan, our historic rule to cut carbon pollution from the power sector, the largest source in the U.S. economy. Our plan puts the United States on track to slash carbon pollution 32 percent below 2005 levels by 2030. And the cuts to smog and soot that come along with these reductions will lead to major health benefits for kids and families.

And EPA is taking a host of additional steps to push our progress even further. We’re doubling the distance our nation’s cars go on a gallon of gas by 2025. We’ve taken four separate actions to curb methane emissions from the oil and gas sector. We’re acting on climate-damaging Hydrofluorocarbons (HFCs), domestically, internationally, and through voluntary programs with industry. We set standards for medium-and heavy-duty vehicles and are now going even further with a proposal that will reduce 1 billion tons of emissions.

I’m confident these actions will stand the test of time. Why? Because EPA has a 45-year legacy of finding lasting solutions to difficult environmental problems. In that time, we’ve cut air pollution by 70 percent while our nation’s economy has tripled.
In the U.S., we’re already seeing clean-energy innovations being rewarded. Today, the U.S. uses 3 times more wind power, and 20 times more solar than when President Obama first took office. Jobs in the solar industry are growing faster than in any other sector of our economy—good-paying jobs that grow opportunity in the communities that need it most. Our actions under President Obama’s leadership build on that trajectory.

And we’ve seen time and again the American people are ready to act on climate now. We heard from millions of people on our initial proposal for the Clean Power Plan. We heard from states, utility companies, environmental organizations, and communities across our country. What we heard is that people want to stop talking and start doing. In poll after poll, a majority of Americans say they want climate action. That’s how we know our actions will endure.

But we also know that no country can solve this challenge alone.

That’s why I’m so encouraged by the ambitious commitments we’re seeing from nations around the world. Heading into the COP-21, 180 countries, representing more than 90 percent of greenhouse gas emissions already submitted national plans to reduce their emissions. That’s big.

Here in Paris, our collective efforts are finally aligning. Now is our time.

For the sake of our children and grandchildren, it’s time to come together and do what’s necessary to protect our common home.
